ABSTRACT:
A flavor-retaining multi-layer plastic container comprising an intermediate layer of a cyclic olefin copolymer and inner and outer layers of a non-cyclic olefin resin or an ethylene/vinyl alcohol copolymer jointed together via an adhesive, effectively eliminating the degradation in the adhesion when the container is filled with fragrant components and after the elapse of time. The flavor-retaining plastic multi-layer container comprises, inner and outer layers of a non-cyclic olefin resin, and an intermediate layer of a cyclic olefin copolymer adhered together via adhesive resin layers, wherein said adhesive resin is a linear very-low-density polyethylene having a density of from 0.800 to 0.910 g/cm.sup.3 obtained by the copolymerization of an ethylene with an .alpha.-olefin of an amount of from 6 to 20 mol % per the resin, or is an acid-modified product thereof.
